One of my "santa's not real" moments of computing was realizing how much static and dynamic libraries fucking suck. This cannot be overstated, and is illustrated perfectly by the heroic efforts of software vendors to get away from them.

Okay, a few functions like fopen are fine - but even those are syscall wrappers IRL. But every OS seems to have concluded, that in the place of API calls, one should rather have streams of text (UNIX) or binary messages (Windows, also a bunch of Linux desktop stuff, like Wayland), or File I/O.

Basically a major motivation behind JIT langauges (C#/.NET certainly) was an effort to get away from dynamically linked libraries,

Even DOS didn't really have libraries, you had peripherals mapped to memory at certain addresses, and a set of interrupts, and that was it.

These single file Go and Rust programs read and write stdio and/or network, which is a reasonable solution to a lot of problems, but certainly not all of them, especially in the interactive space.
